Run-blocking stats

Adjusted Line Yards: One of only two opponent-adjusted numbers on the page, this aligns with the ALY figure FO tracks for the NFL and is presented on a scale in which 100.0 is perfectly average, above 100 is good, below 100 is bad.

Standard Downs Line Yards per Carry: The raw, unadjusted per-carry line yardage for a team on standard downs (first down, second-and-7 or fewer, third-and-4 or fewer, fourth-and-4 or fewer).

Passing Downs Line Yards per Carry: The same unadjusted averages for rushing on passing downs.

Opportunity Rate: The percentage of carries (when five yards are available) that gain at least five yards, i.e. the percentage of carries in which the line does its job, so to speak.

Pass-blocking stats

Adjusted Sack Rate: An opponent-adjusted version of a team's sack rate -- sacks divided by (sacks plus passes), presented on a scale in which 100 is perfectly average, above 100 is good, below 100 is bad.
